Paper Summary

The study analyzed different coal pillar sizes in a mine with shallow depth and thick sand above. Using numerical simulations, the researchers determined the optimal coal pillar size for mining in this specific mine. This information allowed them to establish the maximum coal mining rate for the mine.
